In April I will have one night in Dallas and I need to book a hotel. I'll have about 36 hours to explore and all I know I want to do is visit the Sixth Floor Museum. I'd love to keep my hotel under $200 and if possible have a complimentary breakfast. I'm not fussed by which chain I stay at which will shock some of you. I just want somewhere clean and safe and near the museum. What do my Dallas experts recommend?
